This game came with Secucom just like SPORE. These people never really learnt do they, the more you try to resist / prevent the more illegal download will be made (SPORE recorded the highest illegal download in history of gaming)

Pros:

- Considering the installer is only 3.8GB, quite a lot of stuff packed in it.
- Seamless map travelling.
- Crazy good graphics engine. Can play on all high with 1280x960 2x AA DX10 on my HD3870 no lag at all.
- Quite realistic (weapon jams, cars break down but can be fixed, etc.)
- Map system pretty unique.

Cons:

- Too much travelling around.
- FPS controls a bit too clunky, can't lean left or right, hard to sneak since no prone stance.
- Weapon jams are a bloody killer in firefights. Not to mention weapon ammo is limited.
- Have to develop double focus to use the map properly, lol.

Overall, quite an impressive game though.

i don't get any lock-up though i alt-tab few times onto desktop and back to the game, could be your pc's problem??
